基于UAV-RS虚拟仿真系统的教学模式探究

Research on Teaching Mode Based on UAV-RS Virtual Simulation System

针对无人机和遥感测绘(unmanned air vehicle for remote sensing,UAV-RS)相关专业在实际教学中存在的问题,如设备资源和实验时间无法满足学生需求,野外作业中无人机的安全难以管控,天气和环境条件要求苛刻等,以无人机遥感测绘外业为仿真对象,设计开发了虚拟仿真系统,改革实训教学模式。仿真系统确立了无人机飞行操控、地面场景模拟和遥感图像获取3个模块,引导学生自主完成无人机遥感测绘外业过程。评估实验中经过仿真系统学习的学生(实验组)的项目完成率为:初级90%、中级80%、高级75%,均明显高于对照组。表明基于仿真系统的教学模式可提升UAV-RS的外业教学效果,提高复杂项目完成率,并能够激发学生自主学习的积极性。

For the problems existing in the actual teaching of unmanned air vehicle for remote sensing(UAV-RS),such as:limited equipment resources and experimental time cannot meet students'needs for practical training,difficult to control human and machine safety in field operations,demanding weather and environmental conditions,the virtual simulation system is designed and developed with UAV-RS field work as the simulation object to reform the practical teaching mode.The simulation system has established three modules:UAV flight control,ground scene simulation,and remote sensing image acquisition,which can guide students to independently complete the field work process of UAV-RS.In the system application evaluation test,the project completion rate of students(test group)who have learned through the simulation system is:90% at the primary level,80% at the middle level,and 75% at the advanced level,which is significantly higher than that of the control group.The results show that the teaching mode based on the simulation system can improve the field teaching effect of UAV-RS;improve the completion rate of complex projects,and stimulate students'enthusiasm for independent learning.
